(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2006)The adsorption of methylene blue onto bentonite in a batch adsorber has been studied. Three kinetic models, the intraparticle diffusion equation and the pseudo first and second order equations, were selected to follow the ...
-
(MARCEL DEKKER INC, 1997)The removal of cobalt (II) ion from aqueous solutions, by adsorption on activated carbon prepared from the rice hulls (ACRH), has been investigated depending on pH, activated carbon dosage, contact time, initial metal ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2003)The phosphate removal potential of alunite, a low cost and abundantly available material, has been investigated. The effects of calcination temperature and time of alunite, adsorbent particle size, pH and initial phosphate, ...
-
(ELSEVIER SCIENCE BV, 2003)dAn attempt to alleviate the problem caused by the presence of reactive dyes in textile effluents was undertaken. Since alunite is a very abundant and inexpensive, we decided to experiment with it as a potential adsorbent ...
-
(PARLAR SCIENTIFIC PUBLICATIONS (P S P), 2009)The removal of textile dyes (CI acid blue 40 and CI basic blue 41) from aqueous solutions, by adsorption on activated carbon prepared from rice hulls (ACRH), have been investigated depending on pH, activated carbon dosage, ...
-
(GLOBAL NETWORK ENVIRONMENTAL SCIENCE & TECHNOLOGY, 2012)Water hyacinth Eichhomia crassipes was found to have biosorption capacity for cationic dyes, malachite green and methylene blue from aqueous solutions. To evaluate the biosorption capacity and characteristics, the effect ...
-
(ELSEVIER SCIENCE BV, 2008)The biosorption of Cu(II) from aqueous solutions by mimosa tannin resin (MTR) was investigated as a function of particle size, initial pH, contact time and initial metal ion concentration. The aim of this study was to ...
-
(INDERSCIENCE ENTERPRISES LTD, 2008)The biosorption of lead onto mimosa tannin resin is studied using a batch sorber. The experimental isotherm data were analysed using the Langmuir, Freundlich and Temkin equations. The equilibrium data fit well in the ...
-
(PARLAR SCIENTIFIC PUBLICATIONS (P S P), 2005)A method for the preconcentration of Au (III), Pd (II) and Cu (II) is proposed using a minicolumn filled with silica gel modified by 3-[2-(2-aminoethylamino)ethyl-amino]propyl group (AEAEAP-SG). The retained analytes on ...
-
Competitive biosorption of Pb2+ Cu2+ and Zn2+ ions from aqueous solutions onto valonia tannin resin (ELSEVIER SCIENCE BV, 2009)Competitive biosorption of Pb2+,Cu2+ and Zn2+ on valonia tannin resin (VTR) present in binary and ternary mixture were compared with the single metal solution. The effects of the presence of one metal ion on the biosorption ...
-
(ELSEVIER SCIENCE BV, 2006)The adsorption of phosphate onto alunite in a batch adsorber has been studied. Four kinetic models including pseudo first- and second-order equation, intraparticle diffusion equation and the Elovich equation were selected ...
-
(PARLAR SCIENTIFIC PUBLICATIONS (P S P), 2017)In the present study, it was aimed to assess the genotoxic potentials of [4,4-Dimethyl-2,6dioxocyclohexylidene) methylamino) benzene sulfonamide] (2b) and [4-((1,3-Dimethy1-2,4,6trioxo-tetrahydropyrimidin-5(6H)-ylidene) ...
-
(HARD, 2013)This paper investigated concentrations of heavy metals in roadside surface soil samples collected from the D-100 highway in Sakarya, Turkey. The sequential extraction procedure has been applied to 24 soil surface samples ...
-
(SPRINGER, 2012)A BCR-sequential extraction procedure for the determination of extractable heavy metals was applied to sediments of various rivers and lakes. There are many rivers basins in Turkey. Sakarya River Basin is one of the most ...
-
(INDERSCIENCE ENTERPRISES LTD, 2002)This paper describes the determination of lead and nickel in soil samples from Kinali-Sakarya highway side, near Lake Sapanca. Lake Sapanca is the drinking water source for Sakarya city and its environment. This highway ...
-
(PARLAR SCIENTIFIC PUBLICATIONS (P S P), 2017)In the present work, the aim is to determine seasonal changes in the concentrations of Cd, Cr, Cu, Fe, Pb, Mn, Ni and Zn in the water of Sapanca Lake and to determine the water quality. Sapanca is one of lakes which can ...
-
(PARLAR SCIENTIFIC PUBLICATIONS (P S P), 2013)In the present study, airborne particulate matters based on particle sizes were aimed to be investigated experimentally. Sample solutions were FAAS-analyzed for Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn elemental contents. According ...
-
(PARLAR SCIENTIFIC PUBLICATIONS (P S P), 2009)A preconcentration technique, which includes Amberlite IR-120 cation exchange resin, was applied for the determination of thallium traces in river water. Analysis of synthetic thallium solutions consistently yielded >95% ...
-
(DR JYOTI GARG, 2013)In this work, Dandelion (Taraxacum officinale) polyphenol oxidase immobilized on calcium alginate beads was used for the successful and effective decolorization of textile industrial effluent. Polyphenol oxidase (PPO) ...
-
(SPRINGER, 2017)Macro- and micronutrient availability in high-pH soil is a major constraint in crop production especially for the sensitive plants, such as kiwi fruit. A field study was conducted to investigate the multiyear effects of ...
